This Foam-Control EPS energy savings calculator provides an estimate of energy savings by adding Foam-Control EPS insulation to an existing wall.
*Disclaimer: Energy costs for your project will vary depending on the building envelope design/installation, weather conditions, and usage. The calculator assumes the following: 15% window area, 50% reduction in air leakage with taped EPS sheathing joints for framed walls, natural gas for heating, and electricity for cooling. This information is intended for comparison purposes only and should not be used to determine the size of HVAC equipment. In order to determine your specific energy costs, consult a local HVAC professional to complete ACCA Manual J calculation.
